Abstract

In this article, the two-temperature model and the mechanism of effective interaction potentials are used to study the thermal relaxation of hot and dense non-isothermal plasma fuels such as DT, D³He, and P¹¹B. In this work, we do not consider the ion and electron temperatures to be the same because the temperature inside the electron and ion subsystems reaches equilibrium much faster than the temperature between electrons and ions. This is due to the difference between the masses of ion and electron. Simulations and calculations for fusion by confinement are very complex because many different physical processes occur and it takes a lot of time to do these calculations. Therefore, we used the method of effective interaction potentials for the first time in this work because this method can provide accurate and fast calculations for dense plasmas. The effective interaction potentials include two parts: (a) charge overlap effects at long distances and (b) quantum effects at short distances. We calculate the stopping power, energy absorption, transfer coefficients, deceleration time, and temperature relaxation related to non-isothermal dense hot plasma of DT, D³He and P¹¹B fuels and select their optimal ones.
